[0053] Example 1

[0054] See attached Figure 1 , Figure 1 This is a flow chart of the main steps of the method for analyzing deformation of a prefabricated power pipeline corridor structure according to an embodiment of the present invention. Figure 1 As shown, the deformation analysis method of the power prefabricated pipe gallery structure in the embodiment of the present invention mainly includes the following steps:

[0055] Step S101: Obtain additional loads at each node of the prefabricated power pipeline corridor structure under the action of orthogonal strip loads on the ground surface;

[0056] Step S102: determining the vertical displacement of each node of the prefabricated power pipe gallery structure based on the additional load at each node of the prefabricated power pipe gallery structure.

[0057] In this embodiment, the additional load at each node of the power prefabricated pipe gallery structure under the action of orthogonal strip loads on the surface is calculated based on the Boussinesq solution. The longitudinal discretization diagram of the power prefabricated pipe gallery structure is constructed as shown in the figure below: Figure 2 As shown;

[0070] In this embodiment, after determining the vertical displacement of each node of the prefabricated power pipe gallery structure based on the additional load at each node of the prefabricated power pipe gallery structure, the method includes:

[0071] Monitor the vertical displacement of each node of the power prefabricated pipe gallery structure, and send an alarm signal when the vertical displacement of each node of the power prefabricated pipe gallery structure exceeds a first preset range.

[0072] In this embodiment, after determining the vertical displacement of each node of the prefabricated power pipe gallery structure based on the additional load at each node of the prefabricated power pipe gallery structure, the method includes:

[0073] Determining the alarm characteristics of the power prefabricated pipe gallery structure based on the vertical displacement of each node of the power prefabricated pipe gallery structure;

[0074] Monitor the alarm characteristics of the power prefabricated pipeline gallery structure and send an alarm signal when the alarm characteristics of the power prefabricated pipeline gallery structure move beyond its corresponding preset range.

[0075] In one embodiment, the alarm characteristics of the prefabricated power pipeline corridor structure are as follows:

[0076]

[0077] In the above formula, θ is the longitudinal rotation angle of the power prefabricated pipe gallery structure, h is the buried depth of the pipe gallery, and w is the vertical rotation angle of the power prefabricated pipe gallery structure. i-1 is the vertical displacement of the i-1th node of the power prefabricated pipeline corridor structure, w i+1 is the vertical displacement of the i+1th node of the prefabricated power pipeline corridor structure.

[0078] In one embodiment, the alarm characteristics of the prefabricated power pipeline corridor structure are as follows:

[0079]

[0080] In the above formula, M is the longitudinal bending moment of the power prefabricated pipe gallery structure, EI is the longitudinal bending stiffness of the power prefabricated pipe gallery structure, h is the buried depth of the pipe gallery, and w is the vertical bending moment of the power prefabricated pipe gallery structure. i-1 is the vertical displacement of the i-1th node of the power prefabricated pipeline corridor structure, w i+1 is the vertical displacement of the i+1th node of the power prefabricated pipe gallery structure, w i is the vertical displacement of the i-th node of the power prefabricated pipeline corridor structure.

[0081] In one embodiment, the alarm characteristics of the prefabricated power pipeline corridor structure are as follows:

[0082]

[0083] In the above formula, Q is the longitudinal shear force of the power prefabricated pipe gallery structure, EI is the longitudinal bending stiffness of the power prefabricated pipe gallery structure, h is the buried depth of the pipe gallery, and w ...i-1 is the vertical displacement of the i-1th node of the power prefabricated pipeline corridor structure, w i+1 is the vertical displacement of the i+1th node of the power prefabricated pipe gallery structure, w i is the vertical displacement of the i-th node of the power prefabricated pipeline corridor structure, w i-2 is the vertical displacement of the i-2th node of the power prefabricated pipeline corridor structure, w i+2 is the vertical displacement of the i+2th node of the prefabricated power pipeline corridor structure.

[0084] In a specific implementation, the influence of orthogonal strip uniformly distributed load on the existing pipeline corridor in a certain area is analyzed as an example. The soil parameters of the site are shown in Table 1. The longitudinal bending stiffness of the pipeline corridor EI = 5.148×10 8 kN / m 2 , the buried depth of the tunnel is h 2.5m. There is an orthogonal strip load on the ground surface at the tunnel location. The load width is b = 15m (two-way four-lane), and the load size is q = 20kPa. The strip load and the tunnel location are as follows Figure 3 As shown in Figure 2. Research indicates that the load impact range is three times the load width. To satisfy Pasternak's infinite beam assumption, the longitudinal length of the tunnel is assumed to be 15 times the load width. The vertical displacement of the tunnel caused by a uniformly distributed orthogonal strip load on the ground is calculated.

[0085] The buried depth of the tunnel corridor is 2.5m, and the height of the tunnel corridor is 3.95m. According to Table 1, the elastic compression modulus of the foundation soil layer below the tunnel corridor is E s =3.2×4=12.8MPa.

[0086] Table 1

[0087]

[0088] The width of the orthogonal strip load on the ground surface is 15m, and the load size is 20kPa. According to the Boussinesq solution, the additional stress generated at the axis of the tunnel can be obtained as follows: Figure 4 The maximum additional stress generated at the corridor axis is 19.2 kPa. The primary range of additional stress is from -20 m to 20 m, approximately three times the load width. Beyond this width, the additional stress is approximately zero.

[0089] According to the Pasternak foundation model:

[0090]

[0091] In the above formula, t is the depth of tunnel deformation in the Pasternak foundation model, B is the width of the tunnel or pipeline corridor, and V is s is the Poisson's ratio of the soil.

[0092] By solving the above equations using MATLAB software, we can obtain the vertical displacement of the corridor axis under the action of orthogonal strip uniformly distributed loads on the surface. Figure 5 The vertical displacement of the tunnel under the surface strip load is shown in the figure. The additional stress causes a displacement of 5.5 mm. The primary deformation zone is between -40 m and 40 m, approximately six times the load width (15 m). Outside this range, the tunnel experiences upward deformation, but the deformation is minor.

[0093] Figure 6 This is the longitudinal bending moment diagram of the corridor. The bending moment value is positive when the upper end of the corridor section is compressed and the lower end is stretched. Figure 5 and Figure 6 It was found that there is an obvious corresponding relationship between the bending moment value of the corridor and the vertical displacement of the corridor, and the change of the bending moment reflects the change of the vertical bending moment of the corridor.
